RELATED APPLICATIONS

The present application claims priority under 35 U.S.C. § 119 to U.S. Provisional Application No. 62/960,489, entitled “Collapsible Hard-Sided Cooler”, filed on Jan. 13, 2020, the entirety of which is incorporated by reference herein.

TECHNICAL FIELD

The present disclosure relates generally to coolers, and more particularly, to a collapsible hard-sided cooler.

BACKGROUND

Coolers, ice chests, ice boxes, or the like are commonly used to store contents (e.g., food, beverages, etc.) and keep the contents cool. Some coolers are hard-sided and may provide the performance and durability desired by a user. However, because hard-sided coolers are typically rigid, such coolers tend to take up more space than desired the coolers are not in use. Such hard-sided coolers can be inconvenient to store and to transport when not in use. While soft-sided coolers are collapsible, and thus, and may be convenient to store and transport, soft-sided coolers may lack the performance and durability that may be desired by a user. Thus, a hard-sided cooler that is collapsible into a smaller size may be desirable.

Referring to FIGS. 1-4, in some example embodiments, the end panel 106 may be attached to the section 120 of the frame 110, and the end panel 206 may be attached to the section 208 of the frame 110. For example, an attachment tab 404 of the end panel 206 may be inserted or snapped in a notch 408 in the section 208 of the frame 110, and an attachment tab 406 of the end panel 206 may also be inserted or snapped in a notch 410 in the section 208 of the frame 110. The attachment tabs 404, 406 may be attached to the section 208 using the snap-on attachment mechanism shown in FIG. 3 such that the panel 206 is rotatably attached to the frame 110. In some alternative embodiments, other rotatable attachment means such as one or more rods that end through the frame 110 and the end panel 206, may be used. In some alternative embodiments, the end panel 206 may include a single attachment tab or more than two attachment tabs for attaching the panel 206 to the frame 110. In some alternative embodiments, the end panel 106 may be attached to the frame in a similar manner as the upper front panel 112 is attached to the frame 110.

In some example embodiments, the end panel 106 may be rotatably attached to the section 120 of the frame 110 in a similar manner as the end panel 206. To illustrate, the attachment tab 412 of the end panel 106 may be inserted or snapped in a notch 414 of the section 120 of the frame 110, and a second attachment tab of the end panel 106 may be inserted or snapped in a second notch in the section 120 of the frame 110. The attachment tabs of the end panel 106 may be attached to the section 120 using the snap-on attachment mechanism shown in FIG. 3 such that the panel 106 is rotatably attached to the frame 110. In some alternative embodiments, other rotatable attachment means, such as one or more rods that end through the frame 110 and the end panel 106, may be used. In some alternative embodiments, the end panel 106 may include a single attachment tab or more than two attachment tabs for attaching the panel 106 to the frame 110. In some alternative embodiments, the end panel 106 may be attached to the frame 110 in a similar manner as the upper front panel 112 is attached to the frame 110.

In some example embodiments, the end panels 106, 206 are in contact with the base 108 when the cooler 100 is un-collapsed as shown in FIGS. 1-4. For example, the end panel 106 may be rotated with respect to the frame 110 to a vertical position as shown in FIGS. 1 and 4 and held in place by friction between the end panel 106 and the base 110. The end panel 206 may be rotated with respect to the frame 110 to a vertical position as shown in FIGS. 1, 2, and 4 and held in place by friction between the end panel 106 and the base 108. To rotate the end panels 106, 206 toward the cavity 402, a person may push each panel 106, 206 inward with enough force to overcome the friction between the end panel 106, 206 and the base 108.

In some example embodiments, the upper front panel 112, the lower front panel 114, the upper back panel 202, the lower back panel 204, and the end panel 106, 206 define the cavity 402 of the cooler body 102 when the cooler 100 is un-collapsed as shown in FIGS. 1-4. When the liner 200 is inserted in the cavity 402 of the cooler body 102, a perimeter 416 of the liner 200 may snap on to the frame 110 retaining the liner 200 in the cavity 402 while allowing the lid 104 to fully cover the cavity 402 when the lid 104 is closed as more clearly shown in FIG. 1.

In some example embodiments, the strap 124 may be made from a fabric or another suitable material as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure. In some example embodiments, the base 108 and the frame 110 may be made from polyurethane and/or polyethylene or from another suitable material as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure. The base 108 and the frame 110 may be made using blow molding or injection molding methods. In some example embodiments, the panels 110, 114, 202, 204, 106, 206 may be made from polyurethane and/or from another suitable material as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure. The panels 110, 114, 202, 204, 106, 206 may be made using blow molding and may be foamed or air filled.

FIG. 5 shows the hard-sided collapsible cooler 100 of FIG. 1 partially collapsed according to an example embodiment, and FIG. 6 shows the hard-sided collapsible cooler 100 of FIG. 1 fully collapsed according to an example embodiment. Referring to FIS. 1-6, in some example embodiments, the cooler 100 may be fully collapsed as shown in FIG. 6. For example, starting from the un-collapsed configuration shown in FIGS. 1 and 2, a person may rotate the end panels 106, 206 inward toward each other by pushing on the panels 106, 206 closer to the base 108 than the frame 110. The end panels 106, 206 remain attached to the frame 110 as the end panels 106, 206 are rotated. Each end panel 106, 206 may be rotated to a substantially horizontal position below the lid 104. For example, the end panels 106, 206 may be rotated into a horizontal plane that is substantially perpendicular to the un-collapsed positions of the end panels 106, 206. When the end panels 106, 206 are being rotated inward to collapse the cooler 100, the end panels 106, 206 may the liner 200 push inward and upward such that the liner 200 becomes positioned between the end panels 106, 206 and the lid 104.

In some example embodiments, after rotating the end panels 106, 206 inward such that the end panels 106, 206 are substantially in horizontal positions, the user may collapse the upper front panel 112 and the lower front panel 114 as well as the upper back panel 202 and the lower back panel 204, for example, by pushing the panels inward. For example, the user may collapse the upper front panel 112 and the lower front panel 114 by pushing inward on the upper front panel 112 and/or the lower front panel 114 close to attachment sections of the upper front panel 112 and/or the lower front panel 114. The user may collapse the upper back panel 202 and the lower back panel 204 by pushing inward on the upper back panel 202 and/or the lower back panel 204 close to attachment sections of the upper back panel 202 and the lower back panel 204.

In some example embodiments, the upper front panel 112 may remain attached to the frame 110 and to the lower front panel 114 while the cooler 100 is being collapsed and after the cooler 100 is collapsed. The upper back panel 202 may remain attached to the frame 110 and to the lower back panel 204 while the cooler 100 is being collapsed and after the cooler 100 is collapsed. The lower front panel 114 may remain attached to the base 108 and to the upper front panel 112 while the cooler 100 is being collapsed and after the cooler 100 is collapsed. The lower back panel 204 may remain attached to the base 108 and to the upper back panel 202 while the cooler 100 is being collapsed and after the cooler 100 is collapsed. The cooler 100 may be transformed from the partially collapsed configuration shown in FIG. 5 to the fully collapsed configuration shown in FIG. 6 by pushing down on the lid 104 of the cooler 100.

In some example embodiments, the steps of collapsing the cooler 100 may be performed in the reverse order to un-collapse the cooler 100 from the collapsed configuration shown in FIG. 6. For example, lid 104 may be pulled upward, and the upper front panel 112 and the lower front panel 114 as well as the upper back panel 202 and the lower back panel 204 may be stretched out to the vertical positions shown in FIGS. 1 and 2. The end panels 106, 206 may be rotated out until the end panels 106, 206 are stopped by the base 110 at the vertical positions of the end panels 106, 206 shown in FIGS. 1 and 2.

By using the base 108 as well as the panels 106, 206, 112, 114, 202, 204 that serve as hard-sided walls, the hard-sided collapsible cooler 100 can provide the performance and durability of a hard-side cooler while providing the collapsibility of a soft-side cooler. In some example embodiments, the height of the collapsed hard-sided collapsible cooler 100 as shown in FIG. 6 may be less than 50 percent the height of the un-collapsed hard-sided collapsible cooler 100 as shown in FIG. 1.

FIG. 7 shows a stack of multiple hard-sided collapsible coolers 702-706 that are fully collapsed according to an example embodiment. Referring to FIGS. 1-7, in some example embodiments, each cooler of the hard-sided collapsible coolers 702-706 may correspond to the hard-sided collapsible cooler 100 that is in a fully collapsed configuration in FIG. 6. The hard-sided collapsible cooler 100 may be designed to be stackable as shown with respect to the hard-sided collapsible coolers 702-706. The collapsibility of the hard-sided collapsible coolers 702-706 may result in significant space saving during storage and transportation of the hard-sided collapsible coolers 702-706.

FIG. 8 shows a perspective front view of a hard-sided collapsible cooler 800 according to another example embodiment. In some example embodiments, the cooler 800 is substantially similar to the cooler 100.
